Abstract

We present differential photometry of AK Cnc obtained during its March 1995 superoutburst. Superhumps with amplitude of 0 m.2 appeared within 4 days after maximum with a period of 0 d.06749(1). This result is used to estimate a likely orbital period of 0 d.065(2) and a mass ratio (M 2/M 1) of 0.21. Photometric maxima and timings of 26 recorded outbursts imply an average cycle length of 47 days.
